4 8s in 4th or 6th or 8 8s in a slot port

Have 4 hds2.108s in a slot port on 3k, decided back seat is gone, so I want to wall b pillar back or maybe b pillar back but lower than rear window, idk a definant plan yet. I haven't went out an measured available space but I'd easily say 12 cubes ( just thinking of my 3cube box stacked 4 times would easily fit), would I get better results with a 4th or 6th or just wall it off and add 4 more 8s ( for the time being 4 maybe 8 more depends on funds ) in a slot? I'm more I'm for ideas at this point but I've given up hope for the rear seat ever being used and always want more bass. Probably gonna add another set of pioneer pro 6.5s and another set of pioneer pro 3.5s too. But have wood sitting and would make wall modular ( sectioned off in 3cube slot port boxes so I could add subs as I could afford em. Never designed a bandpass so not sure what to expect or what 4 8s would even do in one ,or if my 8s will even work in that style enclosure.

2009 Silverado 1500, 7.5" lift, 37x12.50r17s, Built Gen 4 5.3L ( 4.8l flat pistons, decked 243s, SS2 Cam, Pac 1218 springs, ported intake, 120mm TB, Long tubes, 3" duals HP tuner software tuned by me), 4l80e swapped and 4.56 gears. All done by me. stereo is Pioneer avh 600ex, all stinger rca, jp23 v1.5, skar rp150.4, and hertz hpd4. 2 SHCA 6.5 8ohm, 1 SHCA 3.5", and 1 DS18 tw120pro in each door. The 3.5 mid and 3.5" tweeters are powered by the skar rp150.4, the 6.5s are powered by the hertz bridged @4 ohms. Dual runs   of 3/0 welding cable, 300a alternator, 2 Vmax AGMs up front. current sub is a AB XR 12 ( dual 2 ohm) with bottom spider cut out in 2.25 cubes at 32hz

Regular ported 

Walled and ported u say? Will be using single amp at first, untill I get a second one or a bigger one. Amp only puts down 2300@1 ohm, so basically cutting the power to each sub down to half of what they r getting now ( would be just shy of 300 each vs the 800+ they r Etting now) . Think I'd be getting another amp really quickly.  What would u recommend for a port setup? Aero ( single,double, or quad?) ND what size? They really like the 3 cubes they are in now so I'd assume atleast 6 cubes for 8 subs.
